This is an amazing school! I arrived in late 2013, and I graduated in the class of 2017. My years here were magical and life changing. I become a more competent and responsible person, and the opportunities I received in the program were phenomenal. If you want your child to succeed, then the best school for them to attend is this one. I just finished writing my book Comedy Is No Joke! The Stand-up Comics' Guide to Success, and I am moving my comedy show to LA later this September. I wouldn't have been able to accomplish these feats without the knowledge I gained at Delphian.

Before coming to Delphian I knew nothing about where life would take me.
I thought of myself as a pessimistic person. I was overwhelmed with books and lectures. ​I knew I could do so much more, but I couldn’t. I started at the Delphian School four years ago and finally had hope. Delphian has been a journey. It was a journey not like any other journey. It’s been a process and a discovery. I was shown not only the world, but how I could fit into it. ​It’s about challenging yourself a little bit more when you are too tired to stand up. It’s about providing encouragement when you fall. It’s about alerting you when you are lost. It’s about waking you up before everything is too late.
​Delphian an ​has been the shining star in my life! I will be forever grateful.
​Yesterday, I was a student from the Delphian School. Today, I am a proud graduate. I would recommend Delphian to anyone.

The Delphian School has set me on a path to succeed. Before I went to Delphian, I struggled to learn in a large public high school, particularly in math. I couldn’t get help or individual attention for my questions. Subsequently, I lost my confidence in myself and my future. I felt like a failure. My parents and I decided that enough was enough. We looked at our local options, and found Delphian. My parents and I decided I would try Summer at Delphi, and the rest is history. The Delphian school emphasises the student’s personal learning journey. Not only learning and exploring academic subjects, but also cultivating one’s own personal values and strength. The staff all have one goal: to help students succeed on their journey through the school and through life. Their goal shines through in this beautiful school every day. Their educational values shine through in every graduate. I’m very fortunate to study at Delphian, and I’m thrilled to be an alumna, ready for life.
